I don't know the answer to your question but I just want you to be very careful and know that xanax can be addicting. I have never tried it because my psychiatrist will only give me Tranxene. he doesn't like to use Xanax because it is so addicting. The reason I'm asking you to be cautious is because I noticed something you said on another post - that you are happy for the first time because you're on xanax. If it's because it's finally treating your anxiety, that's okay.
